It is believed that there is nothing many inexperienced people can do about how to define a string in C language. therefore, this paper summarizes the causes and solutions of the problem. I hope you can solve this problem through this article.

1. What is a string?

A string is essentially an array of special characters that ends with'\ 0'.

2. What are the points for attention in the process of defining a string

Since a string is essentially an array of special characters that ends with'\ 0', when defining a string, you must ensure that the last element stored in the string is'\ 0'.

When we do not give the specific length of the string, we define the string in this way: the char string name [] = {the elements contained in the string}; we need to manually add'\ 0" to the end of the string, otherwise it is just an array of characters, not the string we need.

When we give the specific length of a string, it is in this way: char string name [string length] = {elements contained in the string}; to define a string, we need to make the string length equal to the actual length of the string + 1, otherwise, it is just an array of characters, not the string we need. For specific examples, please see the specific format of the definition string.

3. Define the specific format of the string 3.1, char string name [string length] = {elements contained in the string}

Note: if we do not add'\ 0'to the elements contained in the string, then the string length should be the actual length of the string + 1.

For example: char name [6] = {'tween,' oval, 'masked,' hitched,'e'}

3.2. char string name [] = {elements contained in the string}

Note: to define a string in this way, you need to write'\ 0' in {}.

For example, char name [] = {'threaded,' oiled, 'masked,' hacked, 'estranged,'\ 0'}; 3.3.The char string name [] = "elements contained in the string"

Note: the underlying principle of defining a string in this way is to convert "TomHe" into {'qualified,' oval, 'masked,' hacked, 'estranged,'\ 0'}.

For example: char name [] = "TomHe"; char name [] = {'titled,' oiled, 'masked,' hacked, 'estranged,'\ 0'}

The specific code is as follows:

# include int main () {char str1 [6] = {'titled,' oiled, 'masked,' Hathaway,'e'}; char str2 [] = {'7','8','8','\ 0'}; char str3 [] = "Tomhe789"; printf ("str1 =% s\ n", str1); printf ("str2 =% s\ n", str2); printf ("str3 =% s\ n", str3)

Return 0;}

Running result:
